Terms

The rules of using Milo. There is one price, it is paid once, and none of this is written to be hard to read — if a sentence here needs a lawyer to understand, that is our mistake and we would like to hear about it.

Last updated August 17, 2026

Who you are agreeing with

Milo is made and run by two parents, Kilian and Penelope. These terms are the agreement between you and us, and they cover the app, this website, and anything bought here. You can reach a human, one of us, at hello@milo.baby.

Using Milo means accepting them. If you do not, the honest answer is not to use it — and if you have already paid, ask for your money back and we will send it.

What Milo is, and what it is not

Milo is a shared log. It records what you and the people you invited put into it, and shows it back to you on every phone in the house. That is the whole product.

It is not a medical device and nothing in it is medical advice. The growth curves are a drawing of numbers you typed against a published reference, not an assessment of your baby. The emergency card is a copy of what you wrote down, not a medical record. If something worries you, call your paediatrician; in an emergency call your local emergency number rather than opening an app.

It is not something to rely on for reminders either. Notifications are best effort, and a phone that is asleep, out of battery or out of signal will not get them.

Your household

A household is the log and the people in it. Whoever creates it invites the rest — the other parent, a grandmother, the night nurse — and chooses what each of them can do.

You are responsible for who you invite, and for the fact that what you are giving them is your baby’s whole record. Remove someone and their access ends; what they already read, they already read.

You need the right to put in what you put in. In practice that means a photo of somebody else’s child, or another family’s details, does not belong in your log without their say.

What it costs

$19.99, once. That unlocks the household — everyone in it, on every device, permanently. There is no subscription, no renewal date, no charge per person, and nothing to cancel.

Anyone in the household can pay it, not only a parent. Once it is paid, nobody in that household is asked for money again.

We may change the price for households that have not bought yet. We will never charge a second time for something already paid for, and there is no higher tier for features to be moved into later — what you unlocked is Milo.

Families invited during the free beta were told it was free, and it stays free for them. That is not a promise somebody has to remember to keep: a household that existed before we started charging has no clock to run out.

Who takes the money

Paddle is the merchant of record for every purchase — Paddle.com Market Ltd, not us. The sale is with them: they take the payment, they charge and remit VAT and sales tax where it is due, and the receipt in your inbox is theirs. Their buyer terms apply to the transaction alongside these.

It also means we never see your card number. Nothing about your card reaches our servers, because it does not pass through them.

Write to us anyway. A refund, a lost code, a charge you do not recognise — hello@milo.baby is a person, and we would rather sort it out ourselves than have you argue with a payments company.

Refunds

Ask within 30 days of paying and you get your money back. No questions, no reason needed, no form. Write to hello@milo.baby.

If you are a consumer in the EU or the UK you also have a legal right to withdraw within 14 days of buying a digital service. Our 30 days is longer and simpler, so use that; the legal right sits underneath it and nothing here takes it away.

After 30 days it stops being a rule and becomes a conversation. Write anyway — we are two people, not a refunds department.

Gift codes

A gift code is bought here and handed over: written in a card, texted, read out at a baby shower. It carries the unlock, and the family who redeems it never pays.

It is a bearer instrument. It is tied to no email address and to no person, and whoever types it in gets the unlock — so treat it the way you would treat cash tucked into a card. Post it in a group chat and the first person to use it has it.

It works for two years from the day it is bought, which is long enough to buy one before the birth. It unlocks one household, once, and cannot be split or partly used.

Lost it? Write to us with the receipt and we will find it. If it was never redeemed, the 30-day refund applies to whoever bought it, the same as anything else here.

Your data is yours, and paying changes nothing about that

Everything you have logged can be exported as CSV from Settings → Data, at any time, without asking us and without waiting for us. It is a button, not a request form.

Paying does not alter a single promise on our privacy page. Your log is not sold, not mined, and never used to train machine-learning models, ours or anybody else’s. Money does not buy us a different relationship with your baby’s record.

If we stop

We are two people. Milo could end — because it does not work as a business, or because life happens.

If that day comes we will tell you by email before it happens, not after, and give you a stated period to take your data out with the export still working. We will not sell the log to whoever wants to buy the users. If Milo is ever handed to somebody else, we will say so first.

The export exists today for exactly this reason. If your record matters to you, take a copy now and again from time to time — that is true of every service you do not run yourself, and this one is smaller than most.

What we do not promise

We do not promise Milo is always up. There is no uptime guarantee and there are no support hours; there are two of us and we answer our own email.

We do not promise it never loses anything. We take backups and we test the parts that matter, but the honest sentence is that software written by two people at night can have bugs — and the export is what makes that survivable rather than final.

If something breaks in a way that matters, tell us. That is not a formality: the feedback tab in the app and hello@milo.baby both reach a person, and it is how nearly everything in Milo got fixed.

When an account can end

You can stop at any time. Export first, then write to us and we will delete your account; if you were the last person in your household, the log goes with it.

We can end an account used to break the law, to harass somebody, or to attack the service — and one trying to resell Milo. If we ever end a paid household for any other reason, we refund what was paid.

A household that has not paid when its trial ends goes read-only, not dark. Every screen, every photo, the whole history and the export keep working; only new entries stop. We are not holding a baby’s record hostage over $19.99.

Liability, in plain words

If we get something wrong and it costs you money, what you can recover from us is limited to what you paid us — which is at most $19.99. That is not a lawyer’s trick. It is the honest size of this thing, and it is why the export matters more than any promise on this page.

Nothing here limits what cannot be limited. We are not excluding liability for death or personal injury caused by our negligence, for fraud, or for the consumer rights your own country gives you and does not allow a website to sign away.

Which law, and where

We are in California, and these terms are governed by California law and its courts.

If you are a consumer in the EU or the UK, that sentence does not take away the protection of your own country’s law, and you can bring a claim where you live. Practically: write to us first. Everything so far has been solved by email.

Changes

If these terms change in a way that matters, we will say so by email rather than quietly editing the page. The date at the top is the last time they changed.

Asking anything

Refunds, gift codes, a charge you do not recognise, or a sentence here that does not make sense — all to the same place, and a person answers: hello@milo.baby. What we do with what you log is a separate page, our privacy policy and nothing on this one changes it.
